It is amazing to think that there are over 130 years worth of Haynes Custom Flutes out there in the world! A subject of frequent communications from all around the globe is a request for the manufacturing date of a Haynes Flute by referencing the serial number.

So we decided to put this resource online to give Haynes Players the opportunity to have an idea of when their precious Custom Flute was made. We hope you find it both useful and interesting!

With records stretching back over a hundred years, there is a LOT of data! With personalized quirks and idiosyncrasies peppered throughout, sometimes things get a little strange. Some serial numbers have been lost entirely, others appear to jump around a little, and certain serial numbers, especially towards the beginning and end of each year, can be a little out of sync.

The entire database from 1900-2005 is here. Use the search function in your web browser (normally Ctrl+F or Cmd+F) to enter the serial number you wish to look up. The manufacturing date and specification will be listed next to the search result. Or simply scroll through the pages (and pages and pages!) of serial numbers going through the years. Look for patterns, palindrome numbers, famous flutes, strange specifications. They’re all there to be explored - enjoy!

Please note - the Wm. S. Haynes Co. do not buy or sell vintage or used Haynes Flutes of any age
if you would like to buy or sell a used or vintage Haynes Flute please contact your nearest Haynes Dealer.

Notes:
Sometimes the date of manufacture has been formatted to show the 1st of the month.
This is not necessarily the case, especially in later years.

1928-1932 were strange years with some flutes showing out of sequence between October to March in each year end and start.
Also, due to a quirk in the numbering, before Haynes went to a broadly sequential system, there was originally a model-based serial numbering convention,
meaning that a handful of flutes in the 10200-12300 range of serial numbers were actually made in 1900, 1901 & 1902.

Most #13XXX flutes were simply not made, mainly due to superstition. However, a total of maybe fourteen #13*** flutes were made in 1943 (we’re honestly not totally sure). So if you have one, it’s quite rare, and was likely made between January and March of 1943.
